Version v0.8.0

Improvements

• Support for writing based on Arrow as the transfer mechanism of the data
  from Python to GDAL (requires GDAL >= 3.8). This is provided through the
  new pyogrio.raw.write_arrow function, or by using the use_arrow=True
  option in pyogrio.write_dataframe (#314, #346).
• Add support for fids filter to read_arrow and open_arrow, and to
  read_dataframe with use_arrow=True (#304).
• Add some missing properties to read_info, including layer name, geometry name
  and FID column name (#365).
• read_arrow and open_arrow now provide
  GeoArrow-compliant extension metadata,
  including the CRS, when using GDAL 3.8 or higher (#366).
• The open_arrow function can now be used without a pyarrow dependency. By
  default, it will now return a stream object implementing the
  Arrow PyCapsule Protocol
  (i.e. having an __arrow_c_stream__method). This object can then be consumed
  by your Arrow implementation of choice that supports this protocol. To keep
  the previous behaviour of returning a pyarrow.RecordBatchReader, specify
  use_pyarrow=True (#349).
• Warn when reading from a multilayer file without specifying a layer (#362).
• Allow writing to a new in-memory datasource using io.BytesIO object (#397).

Bug fixes

• Fix error in write_dataframe if input has a date column and
  non-consecutive index values (#325).
• Fix encoding issues on windows for some formats (e.g. ".csv") and always write ESRI
  Shapefiles using UTF-8 by default on all platforms (#361).
• Raise exception in read_arrow or read_dataframe(..., use_arrow=True) if
  a boolean column is detected due to error in GDAL reading boolean values for
  FlatGeobuf / GPKG drivers (#335, #387); this has been fixed in GDAL >= 3.8.3.
• Properly ignore fields not listed in columns parameter when reading from
  the data source not using the Arrow API (#391).
• Properly handle decoding of ESRI Shapefiles with user-provided encoding
  option for read, read_dataframe, and open_arrow, and correctly encode
  Shapefile field names and text values to the user-provided encoding for
  write and write_dataframe (#384).
• Fixed bug preventing reading from bytes or file-like in read_arrow /
  open_arrow (#407).

Packaging

• The GDAL library included in the wheels is updated from 3.7.2 to GDAL 3.8.5.

Potentially breaking changes

• Using a where expression combined with a list of columns that does not include
  the column referenced in the expression is not recommended and will now
  return results based on driver-dependent behavior, which may include either
  returning empty results (even if non-empty results are expected from where parameter)
  or raise an exception (#391). Previous versions of pyogrio incorrectly
  set ignored fields against the data source, allowing it to return non-empty
  results in these cases.
